A pediatric cognitive screening tool has been shaped in three versions according to school class to assess spatial and temporal orientation, language, reading, writing, drawing, number knowledge, memory, praxis and executive functions in children aged 6-13. It has been standardized on an Italian sample of 807 children. Raw scores were adjusted for critical variables (child's age and parents' education) and a cut-off for the resulting global cognitive score was made available for clinical practice. In line with previous research, adapting the Mini-Mental State Examination to pediatric neuropsychological assessment turned out to be useful in estimating global cognitive functioning in children...

BACKGROUND: A recent hypothesis has suggested that core deficits in goal-directed behavior in obsessive-compulsive disorder (OCD) are caused by impaired frontostriatal function. We tested this hypothesis in OCD patients and control subjects by relating measures of goal-directed planning and cognitive flexibility to underlying resting-state functional connectivity. METHODS: Multiecho resting-state acquisition, combined with micromovement correction by blood oxygen level-dependent sensitive independent component analysis, was used to obtain in vivo measures of functional connectivity in 44 OCD patients and 43 healthy comparison subjects...

BACKGROUND: Recent studies suggest that cortical lesions in multiple sclerosis (MS) substantially contribute to clinical disease severity. The present study aimed at investigating clinical, neuroanatomical, and cognitive correlates of these cortical lesions with a novel approach, i.e. by comparing two samples of relapsing-remitting multiple sclerosis (RRMS) patients, one group with and the other without cortical lesions. METHODS: High-resolution structural MRI was acquired from 42 RRMS patients and 43 controls (HC)...

RESEARCH QUESTION: Is there an association between regular exercise, defined as a structured program of increased physical activity at least 1 month in duration, and improvements in measures of executive functions compared with children who engage in their normal daily activities? CONTEXT: The association between increased physical activity and changes in performance on tasks of executive functions have not been well elucidated in children. Executive functioning is important to intellectual development and academic success in children, and inexpensive, nonpharmacological methods for the treatment of executive dysfunction represent an attractive interventional target...

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder with pathological involvement of upper and lower motoneurons, subsequently leading to progressive loss of motor and speech abilities. In addition, cognitive functions are impaired in a subset of patients. To evaluate these potential deficits in severely physically impaired ALS patients, eye-tracking is a promising means to conduct cognitive tests. The present article focuses on how eye movements, an indirect means of communication for physically disabled patients, can be utilized to allow for detailed neuropsychological assessment...

AIM: Paediatric arterial ischaemic stroke can lead to reduced quality of life (QoL). It is important to identify predictors of QoL to support recovery. We examined long-term QoL after arterial ischaemic stroke concerning different variables. METHOD: Children registered in the Swiss Neuropediatric Stroke Registry and suffering from arterial ischaemic stroke between 2000 and 2008 were included. Two years post-stroke, assessments included intelligence quotient tests for cognitive impairment and modified Rankin Scale (mRS) for neurological impairment; 5 years post-stroke, the Kidscreen-27 was used for QoL, DSM-IV criteria screening was used for attention deficits, and the ABILHAND-Kids was used for manual motor skills...

Traumatic brain injury (TBI) in women experiencing intimate-partner violence (IPV) is common, and IPV afflicts 30 % of women worldwide. However, the neurobiology and related sequelae of these TBIs have never been systematically examined. Consequently, TBI treatments are typically absent and IPV interventions are inadequate. There has been a call for a comprehensive assessment of IPV-related TBIs and their relationship to aspects of women's cognitive and neural functioning. In response, we examined brain-network organization associated with TBI and its cognitive effects using clinical interviews and neuropsychological measures as well as structural and functional Magnetic Resonance Imaging (fMRI) in women experiencing IPV-related TBI...

The new classification of epilepsy stratifies the disease into an acute level, based on seizures, and an overarching chronic level of epileptic syndromes (Berg et al., 2010). In this new approach, seizures are considered either to originate and evolve in unilateral networks or to rapidly encompass both hemispheres. This concept extends the former vision of focal and generalized epilepsies to a genuine pathology of underlying networks. These key aspects of the new classification can be linked to the concept of cognitive curtailing in focal epilepsy...

Objective: Executive cognitive functioning is essential in private and working life and is sensitive to stress and aging. Cardiovascular (CV) health factors are related to cognitive decline and dementia, but there is relatively few studies of the role of CV autonomic regulation, a key component in stress responses and risk factor for cardiovascular disease (CVD), and executive processes. An emerging pattern of results from previous studies suggest that different executive processes may be differentially associated with CV autonomic regulation...
